Pair will star in romantic comedy based on mock auction program

Brad Pitt and Natalie Portman want you to buy what they're sellin'.

Pitt and Portman have signed on for the adaptation of Leanne Sharpton's (deep breath) "Important Artifacts and Personal Property from the Collection of Lenore Doolan and Harold Morris, Including Books, Street Fashion, and Jewelry," according to Variety. The transition from Sharpton's novel to the big screen should be interesting, to say the least: "Important Artifacts" reveals the characters not through narrative but via a mock auction catalog, leaving readers to explore the relationship based on the items for sale and their descriptions.

Instead, Variety says the film will be a romantic comedy with Pitt and Portman in the title roles.

Pitt, 45, will co-star this year in Quentin Tarantino's "Inglorious Basterds." Portman, 27, last starred opposite Scarlett Johansson in "The Other Boleyn Girl."
